BioAmp Processor

RZ5 BioAmp Processor

The RZ5 features one or two ultra fast digital signal processors networked on a novel bus architecture that speeds both onboard communication and memory access. Two Medusa fiber optic input ports and one output port allows the RZ5 to function as either a biological amplifier system or a microstimulator system.

Used with the Medusa battery powered preamplifiers, the system provides simultaneous ~25 kHz acquisition on every channel, fiber optic isolation, and the power of user-programmable real-time DSPs. The system’s versatile design allows you to switch from extracellular recording to EMGs simply by changing headstages.

Used with a MS16 stimulus isolator the system functions as a programmable current stimulator capable of delivering complex microstimulation patterns simultaneously across multiple microelectrode channels.

PCM analog outputs support a wide variety of signal production tasks, including control of motors and monitoring analog signals during acquisition.

For researchers who wish to transfer data across a network to another PC, we offer an optional RZ UDP Ethernet interface.

The RZ5 is rack mountable in a standard 19" rack and is 3 U (5 1/4") tall.

For improved bandwidth or high channel count electrical stimulation, consider the RZ5D.

For systems with up to 256 recording channels, consider our RZ2 base station and PZ2 preamplifiers.

RZ UDP Interface: The RZ Communications Interface is an optional interface for RZ processor devices that includes a UDP Ethernet connection and a serial port connection.

The serial port can support baud rates up to 115200. The port is a standard 9-pin RS232 connection located on the back of the RZ and occupies one o the RZ's DSP expansion slots. The RS232 port can be directly connected to any device that communicates via serial port, such as head trackers, eye trackers, or a PC.

The UDP interface is designed to transfer up to 200 data values at low rates to or from a PC. The PC may be directly connected through a dedicated Ethernet card located elsewhere on the user’s network, or even in a remote location connected via the internet. The RZ UDP interface is located on the back panel of the RZ processor and accepts a standard Ethernet cable.

Part numbers:
RZ-UDP-20 UDP Ethernet Interface Card

Technical specifications:

Cable Interface:	Standard Ethernet cable (for direct connections to a PC an Ethernet crossover cable is required)
